Adjusting Spark syntax

[Louis DeJardin]

Hello,

As Spark is being used in a real-world application a problem that was
spoken about has surfaced. The expression output syntaxes <%=expr%> $
{expr} and $expr; are all treated the same, but the third one collides
pretty badly with any prototype/jquery javascript that's not in a
static js.

So I'm thinking of taking out the $expr; syntax. Would anyone miss
that?

I've also had an interesting recommendation for a variation on the
conditional syntax.

<p if="x">foo</p>

<test if="x">
  <p>foo</p>
</test>

<test if="x">
  <p>foo</p>
  <else/>
  <p>bar</p>
</test>

<test if="x">
  <p>foo</p>
  <else if="y"/>
  <p>bar</p>
  <else/>
  <p>foo</p>
</test>

Thoughts?

- Lou

I havent seen your parser, but I'd recommend patching it to accept the
proper syntax and ignore others.

$() is completely ignored by nvelocity, however I can't use $.ajax for
instance, which I can deal with by using jQuery.ajax... I take this is
a limitation in nvelocity's parser as $. could also gracefully
ignored.

It's a recursive descent parser declared with a fluent interface. Very
easy to adjust.

What is the parser that you are using?

I couldn't find anything along the lines of a simple open source
parser to use. So it's one I put together heavily inspired by a blog
post from Luke H.

http://blogs.msdn.com/lukeh/archive/2007/08/19/monadic-parser-combinators-using-c-3-0.aspx

I wrote about it a little while ago also. It's pretty dry.
